Revolutionary Carbon Capture Method Integrated into Wastewater Treatment Plants

Joachim Katchinoff and Kevin Vu of Crew Carbon In episode #80 of Open Air’s video series, “This is CDR”, featured Joachim Katchinoff and Kevin Vu from Crew Carbon. This company approaches carbon removal through enhanced weathering in wastewater facilities. Crew Carbon's approach combines nature-based solutions with engineered processes to enhance carbon dioxide removal (CDR) and help combat climate change. Enhanced weathering is the process of accelerating the natural weathering reactions that remove carbon dioxide (CO2) from the atmosphere by exposing rocks to CO2-rich compounds. This process dissolves the rocks and converts CO2 into a ...

OpenAir CDR on Enhanced Rock Weathering: Scaling up climate solutions globally

Dirk Praessler, CEO of Carbon Drawdown Initiative One of the biggest challenges we face today is climate change. Scientists have long-since warned of the inevitable effects of a warming planet, yet despite this urgency, today’s economy continues to run primarily on fossil fuels. Decarbonization – the active capture and storage of CO2 from the atmosphere – is one possible solution. However, as Dirk Paessler, founder and CEO of Carbon Drawdown Initiative explained in a recent “Open Air This is CDR” episode, Decarbonization is “pointless without 90% emissions reduction.” We need to decarbonize the economy while simultaneously pulling ...

Tomatoes, Orchards, and Forests: Studying Reforestation and Remineralization in China

Carbon reduction in China For China, carbon-reduction efforts remain rooted in reforestation and afforestation efforts, as the country keeps planting trees through to 2025.[4] In addition to these efforts, researchers in the People’s Republic have turned their attention increasingly towards enhanced weathering and rock dust application, studying reforestation and remineralization. China has decades of experience with major tree planting projects, for example, in 1978 initiating the so-called “Great Green Wall” project (official name: the Three-North Shelter Forest Program), whose goal is to plant 2,800 miles of tree-based wind breaking forest ...

Remineralization Goes Mainstream: Major media outlets recognize the power of rock dust

Application of silicate material to cropland. Beerling et al. demonstrate that enhanced rock weathering, achieved by adding crushed basalt or other silicate material to soil, is an effective strategy for removing carbon dioxide from the atmosphere. Photo by: Ilsa B Kantola break Last year, the journal Nature published an immensely-popular study on remineralization. With more than 20,000 views, this article may be the most widely-read paper on enhanced weathering to date, and several major media outlets have picked up on it as well. In The Washington Post, Lindsay Layton explains clearly: “Spreading rock dust on the ground could pull carbon ...

Prof. David Manning on Rock Dust: Quarries, Breweries and Beyond

Soils are a critically important natural resource, providing us with 90% of our food, lumber for construction, and natural fibers like cotton. Through plant and microbial activity, soils also play an essential role in shaping Earth’s atmosphere. The amount of carbon cycled through the plant-soil interface every seven years is equivalent to all the carbon in the atmosphere. Soils do all of this while only covering about a quarter of Earth’s surface. Sustainable soil management is therefore essential to mitigating climate change while preserving soil as a resource for future generations. It’s a complicated task. Soil science lies at the inters...

Basalt Rock Dust Increases Carbon Capture Fourfold

A research team within the Leverhulme Centre for Climate Change Mitigation has demonstrated basalt rock dust as a method of improving crop yield and sequestering carbon.

The Leverhulme Centre for Climate Change Mitigation – Advancing remineralization into the mainstream

Responding to climate change is one of the most complicated and one of the most long-term projects humanity has ever undertaken. If we're going to manage this challenge, it's going to involve new policies, new laws, and new ways of behaving. We have to think not of ourselves (that in itself is a challenge for human beings); we have to think of future generations. Oliver Morton, The Economist   The grand challenge A new paradigm for research has taken shape in a ground-breaking effort to mitigate climate change, and remineralization is the focus of this unique new approach. The Leverhulme Centre for Climate Change Mitigation was founded ...
